→Arcane Item Affinity: moving spell completion items (scrolls) into the skill. doing something else with ciphers...
====[[Tome of Prowess (3.5e Sourcebook)/Arcana#Arcane Item Affinity|Arcane Item Affinity]]====
A little knowledge about obscure arcane magical theory goes a long way. With it you can attempt to use arcane spell trigger or spell completion items even if you lack the ability to normally use the spells within them. But your skill with the arcane doesn’t stop there. Arcane magic is based on tricking the world into doing what you wanted it to do all along, and some of those tricks work to coax magic items into working for you even when you lack the prerequisite attributes. If a magic item requires a certain ability score to function, you can try to ignore that requirement as well.</onlyinclude>
For continuous use items with an attribute prerequisite, this check requires a swift action. Otherwise, the action to use this ability is included in the activation action for the item(often the spell's casting time). The DC for this check is equal to the minimum required ability score or 14 + the item's caster level, whichever is higher. If you succeed on the check, the item functions as if you have the minimum required ability score for a period of time based on your check result. You may not attempt this check again during any period while it functions normally. You must wait for the item to stop responding to you before you may make an additional check.
Note that this ability only activates items that are arcane in nature or that have an attribute prerequisite to their use. It only covers those portions of the activation. Items that have an attribute prerequisite but are not arcane, or that have additional non-attribute prerequisites, may not be covered by this ability. In this case, additional checks with other skills may be required.
